Fig. l5 is a perspective view of the U-shaped perforatedmetal screen which incloses the conveyer-shaft.

Our invention is an improved cotton-seed huller and separator. Its object is to provide an improved hulling-cylinder, and also means formounting the same upon its shaft, so that it may be readily removed,reversed, and replaced. It also consists in an improved concave, which,coactin g with the cylinder, may be used without change for grindingcorn as well as 5o for hulling cotton-seed.

It also consists in certain improvements in the separator and its shaftand the arrangement of the separator with relation to the huller.

It iinally consists in certain peculiar arrangements and combination ofparts, all of which will be first fully described in connection with theaccompanying drawings, and then particularly referred to and pointed out6o in the claims. f

In the several figures of the drawings co1- responding parts areindicated by similar reference-letters.

The frame upon which the operative parts of the machine are mountedconsists of the four horizontal beams A, which are framed into the fourupright posts A. The frame formed by the beams A is closed upon the top.To the under side of this frame is 7o secured a U-shaped perforatedmetal screen B, within which the conveyer -shaft C is mounted torevolve. Said shaft is provided with a number of spiralflights C', whichas the shaft C revolves carry the broken seed from the receiving to thedischarge end of the machine, and, acting in the double capacity ofseparator and conveyer, in combination with the inclosed casing, causethe separated kernels to be discharged through the 8o perforated screenB as they are conveyed forward, the greater portion being dischargednear the receiving end, and the less easily separated or less perfectlybroken being carried along and separated by the action of the iiightsuntil at the tail end of the machine only the broken hulls and lintremain in the screen, as clearly shown in Fig. l, to be discharged atthe tail end of the machine.

The ends of conveyer-shaft C are turned off 9o slightly convex toreceive the concave seats in the gudgeons D, which carry the journals E,upon which the shaft revolves. The journals have tapering bores E toreceive bolts F. The end of the shaft C is bored out to meet an apertureat right angles to it, in which aperture is a nut to receive thescrewthreaded end of the bolt F for the purpose of tightening thegudgeons D against the end of the shaft C. The concave face of thegudgeon has a lug or pin E proj eeting from it into the shaft to preventeither turning independent of the other.

Upon one end of the frame A A is mounted the huller, and upon the top ofthis the hopper and feed-roll within it, which, in combination with theseparator mounted in or upon the same frame, comprises a single inachinewhich performs all the operations of liulliiig the seed and separatingtheliulls and lint from the kernels.

There a-re two hoppers shown, the permanent one J, which is employedwhen the inacliiiie is used for cotton-seed, and the taperingren'iovable one X, which is employed should it be desirable to use themachine for grinding' corn,to which use it is also adapted by reason ofthe peculiar construction and arrangement of the hulling-cylinder andconcave, as will be explained hereinafter.

The permanent hopper is provided with a feedroll I, which is locatedjust below its parallel walls.

The rear of the hopper is provided with a gate J, which is hinged at Kand provided with an inwardly-projectiiig flange J', which is adjustablenearer to or farther from the feed-roll I by the set-screw L. A curvedspring L has its lower end secured to the wall 0f the hopper. Its upperend presses against the gate .I and holds the gate closed with elasticpressure, allowing it to yield should the seed tend to clog thefeed-roll. By turning the feed-screw L the operator may regulate thefeed according to the speed of the machine or the condition of the seedun der treatment.

The hulling-cylinder N is a hollow shell cast in a single piece. Theinterior at each end is made tapering inward, as shown at N', and thebore between the inclines at the ends is enlarged, forming the chamberO, so as to save metal and provide against unequal shrinkage. Thecylinder is mounted and secured upon its shaft M by the frusto-eoniealblocks P, which are bored out to fit the shaft M, and have theirexteriors dressed to match into the tapering ends of the cylinder. Theseblocks P are bored, as seen at Q, so as to freely slip over the shaft,and are slit through from the periphery to their central bores, as shownat P', Figs. 5, G, and 7, so that the opposite blocks are drawn in thedirection of each other by the tlirough-bolts R R and nut R. The boltspass through holes Q in the plugs P, as clearly shown in Fig. 4. Theplugs P will be firmly clamped upon the shaft M and held to it byfrictional contact.

Upon the cylinder N is cast a series of ribs S. The spaces ordepressions between the ribs are simple curves S. When the castingleaves the sand, the edges are rough, as seen in Fig. S. The cylinder isfinished for use by centering it in a lathe and grinding the faces ofthe ribs smooth by eiiiery-whcels, after which the shoulders 'il areformed upon each side of the ribs by an einery-wlieel, formingpractically cutting-edges. By reason of the circular depressions betweenthe ribs but little metal need be removed, and the face of the ribsbeing bioad they can be repeatedly sharpened, so that the cylinder willlast a long time. Another advantage incident to the peculiar means formounting the cylinder is that it can be readily removed and replaced orreversed when desired, so that the wear of the ribs is even, and thatwhen the cylinderis once mounted the following as well as the leadingedges may be sharpened, the following edges when the cylinder isreversed end for end becoming the leading or cutting edges. Thusone-half of the labor of mounting the cylinder to be sharpened is saved.Another advantage is that as both edges of the emery-wheel are used insharpening both sides of the ribs it will wear evenly until worn out,thus saving the time and trouble usually necessary to keep the wheel inworking shape when only one edge is used.

The concave V, Figs. l0 and '14, is built up, preferably, of sections,and its inwardly-projecting ribs XV are arranged in zigzag shape and inalternate pairs, preferably two pairs upon each stave or quarter, asclearly showii in Fig. la. The two lines of ribsof each pair are paallel to each other, while each alternate pair is inversely arrangedwith relation to the pair next to iff-that is, the spaces between thealternate pairs are rectangular or diamondshaped, instead of parallel,as between the adjacent ribs of each pair. We find that by so arrangingthe ribs upon .the concave, in combination with the straight ribs uponthe hulling-cylinder, the huller pei'- forms its work moresatisfactorily as a cottonseed huller, and at the same time is renderedeffective as a corn-grinder should it be desirable to use the machine assuch. Each stave or section of the concave has holes W formed in it toreceive the bolts by which the staves are secured in position.

When it is desired to use the huller for grinding corn, the removablehopper X is placed in the position shown in Fig. 11, the conveying or Vends X coming close together just above the feed-roll I. The lower edgesof these pieces are cut out, as shown at X, to nearly conform to theshape of the feedroll I. A wedge Y is used between the upper edge of thepermanent hopper and the inclined ends X of the removable hopper for thepurpose of adjusting the said movable hopper to the proper position.

The machine is driven from a counter-shaft G at the rear end of themachine, upon which is secured a pulley G which receives power from theengine or other source of supply. Upon the opposite end of the shaft Gisa larger pulley H, which transmits power to the hullercylinder, andalongside of this pulley, upon the saine shaft, is a smaller pulley h.,which transmits through belt M. motion to IOO IIO

IZO

the feed-roll I. Upon the same shaft G is also secured a beveled pinionH', which meshes with a similar pinion which is secured upon the end ofthe journal E of the conveyer-shaft C.

What we claim as new is- 1. The combination, substantially ashereinbefore set forth, in a cotton-seed huller, of the hopper, theiiuted feed-roll mounted to revolve therein, a hinged gate having aflange projecting inward in the direction of and above the feed-roll,and a set-screw for adjusting said flange with relation to thefeed-roll, so as to regulate the feed from the hopper.

2. The eonveyer-shaft C, having its ends convexed, in combination withgudgeons D, having concaved seats and provided with tapering bores, andadj Listing-rods for adjustably securing said gudgeons to the end of theshaft, substantially as set forth.

3. The hollow cylinder N, cast in one piece, having ribs S, and curveddepressions between said ribs and shoulders or offsets T, formingcutting-edges upon said ribs, substantially as set forth.

4. A concave V for cotton-seed hullers, substantially as hereinbeforeset forth, having zigzag ribs lV, arranged in pairs, as shown, the ribsof each pair being parallel with each other and the ribs of each pairbeing arranged at an angle to the ribs of the adjacent pair.

5. The combination, substantially as specilied, in a cotton-seed huller,of the hollow hulling-cylinder having longitudinal ribs S and theconcave V, having zigzag ribs arranged in pairs, as shown, the line ofthe ribs of each pair being parallel to each other and at an angle tothe line of the pair adjacent.

6. The combination, substantially as specied, of the reversiblehnlling-cylinder having ribs S, intervening depressions S', andshoulders T, forming edges upon each side of the ribs, and the concaveV, having zigzag ribs W.

7. In a cotton-seed huller, the combination, substantiallj7 asspecified, of the frame A A', the separator consisting of the perforatedscreen B and separator-shaft within'it mounted in said frame, the hullerconsisting of the hulling-cylinder and its concave mounted upon saidseparator, the hopper and its iiuted feed-roll mounted upon the huller,and suitable means, such as shown, to transmit power from the ,sameshaftto the feed-roll, huller, and separator.
